Text Widgets

Agenda

Enhancement in MtiHierarchy widget— Callback support for improved performance

— Sub column support

— Making tree column frozen in place (non-scrollable)

Enhancement in Text widget— Hyperlinks

— Incremental Parsing

Browser Window – MtiHierarchy Widget

Browser Window – MtiHierarchy Widget

Format used to pass information to MtiHierarchy widget for each row is<name> <app data> <label> <tag> <icon> <label> <tag> <icon>…

MtiHierarchy Widget – Callback Support

0xAAAAAA {HINST IN 4 -1} TOP branch vlog_inst

<name>



<name> <app data> <label> <tag> <icon>

Display data for 1st column

<name> <app data>


0xAAAAAA {HINST IN 4 -1} TOP branch vlog_inst Root {} {}

<name> <app data>


Display data for 2nd column

<label> <tag> <icon> <label> <tag> <icon>



<name> <app data>



item ->name




<name> <app data>



item ->name item ->app data




<name> <app data>



item ->name item ->app data item ->data



0xAAAAAA {HINST IN 4 -1} TOP branch vlog_inst Root {} {} 35 {} {}

<name> <app data>



item ->name item ->app data item ->data

<label> <tag> <icon> <label> <tag> <icon> . . .

. . .


<name1> <app data1> <label11> <tag11> <icon11> <label12> <tag12> <icon12>…<name2> <app data2> <label21> <tag21> <icon21> <label22> <tag22> <icon22>…...<nameN> <app dataN> <labelN1> <tagN1> <iconN1> <labelN2> <tagN2> <iconN2>…

Static Data

Changes like addition/deletion of a column does not require any iterations by the widgetDisplay data is provided by the application - takes

fraction of a second



Side Effects

Side Effects – Sorting

Item1Item2.....ItemN


<name1> <name2>.....<nameN>

Application gives us sorted list of “<name>” (item->name pointers)


Application gives us sorted list of “<name>” (item->name pointers)We need the list of sorted “item” pointers.





Application gives us sorted list of “<name>” (item->name pointers)We need the list of sorted “item” pointers.So we create a hash table for item->name

and item pointer

Item1 ->nameItem1Item2 ->name Item2.....ItemN ->nameItemN

Agenda






Sub-columns

Show the fault distribution of instances in various categories and sub-categories

Sub-columns

Show the fault distribution of instances in various categories and sub-categories

Categories and sub-categories should be displayed as in-place expandable/collapsible column.

Sub-columns

Overview of changes

— Enhanced MtiHeirarchy widget protocol to support the sub-column labels as a list of labels instead of column label

<name> <appdata> <sub-label1 sub-label2 sub-label3> <tag> <icon>

Sub-columns

Overview of changes



— Provide APIs for sub-column operations like add, delete, configure, move, etc

Frozen Tree Column

Clipper (a frame) Canvas Sfchildsite (a frame) Columns

Frozen Tree Column

Create two canvases and grid them inside the clipper as column 0 and column 1 of row 0

Frozen Tree Column

1st scrollbar alters the xview of the column 0 such that it scrolls the instance names of the tree column and not the column itself.

2nd scrollbar alters the xview of the 2nd canvas so that the rest of the columns scroll past the tree column.

Agenda






Enhanced Text Widget

Text Highlighting— Text highlighting helps to point out the issues easily

Hyperlinks — Get to the relevant file or information in other windows of

the tool to debug the issues very quickly.

Incremental parsing

Enhanced Text Widget

Yes

Exit

No

Load file in to the text widget (read & write in chuck size =256k)

Calculate the boundary of visible area of text widget.

Start line = B1 and last line = B2.

Highlight the lines as per their category andParse each word and mark it as hyperlink if the

word is filename or instance name or DRC id

If the text between (B1, B2) has already been

parsed
